On parle donc de nutrition minérale des plantes. Toutefois, les plantes sont également capables de respirer, c'est-à-dire d'utiliser l'oxygène pour dégrader la matière organique produite par la photosynthèse et en tirer de l'énergie. Si, à la lumière, respiration et photosynthèse se produisent simultanément, la respiration ...

Trituration. Trituration is the name of several different methods of processing materials. For example, trituration is a process in organic chemistry used to purify crude compounds. The process is such, that a crude compound is created (by any means such as reduction, nitration, etc.) and has solid impurities within it.

This chapter describes a simple procedure for isolating individual cells. Starting with the incubation of whole tissue in an enzyme preparation, which dissociates the pineal gland into small pieces, it continues with gentle trituration and then isolation of single cells through filtration. The procedure takes less than 2 h.
There are four main methods of mixing powders in small-scale operations: Trituration. Spatulation. Sifting. Tumbling. 1. Trituration. The trituration process involves direct rubbing or grinding of hard …
The process of trituration in homeopathy. The first process for manufacturing remedies is called trituration.

trituration: [noun] the act or process of triturating : the state of being triturated : comminution.
It serves to break up the tissue fragments following incubation in the dissociation mix. If done too vigorously, cells will be destroyed lowering viability; too weakly and tissue fragments will be left intact lowering yield. Gentle trituration, using a 10 ml pipette, constitutes filling and emptying the barrel at a rate of about 3.0 ml per sec.

Levigation involves the addition of a liquid to aid in the grinding of a substance into a fine powder, making the process more efficient for substances that are difficult to grind dry. Trituration, on the other hand, usually does not involve liquids and focuses solely on the grinding or rubbing action to reduce substances into fine particles. 9.
